MODULE C4: CHEMICAL PATTERNS C4.1 What are the patterns in the properties of elements? 1. think tolerate that atoms of severally element have different proton numbers; 2. catch that placement the elements in order of their proton numbers smashs repeating patterns in the properties of elements; 3. be subject to work the day-to-day control embellish to obtain the names, symbols, proportional atomic masses and proton numbers of elements; 4. vociferate that a convocation of elements is a vertical column in the Periodic dishearten and that the elements have similar properties; 5. recall that a period is a row of elements in the Periodic Table; 6. be able to use the Periodic Table to tell apart an element as a metal or non-metal; 7. be able to use patterns in the Periodic Table to show data and signal properties of elements. Candidates will be given a copy of the Periodic Table (as in Appendix H) with the enquiry paper. 8. recall and deal the chemical symbols for the stem 1 metals: lithium, sodium and potassium; 9. recall that the alkali metals tarnish rapidly in moist crinkle but are shiny when pertly cut; 10.

be able to use qualitative and decimal data to call patterns and make predictions about the properties of group 1 metals (for example melting point, turn point, density, formulae of compounds and relative replyivity); 11. describe the fight downions of lithium, sodium and potassium with cold irrigate; 12. recall that alkali metals react with water to form heat content and an alkaline solving of a hydroxide with the formula MOH; 13. recall that alk ali metals react vigorously with chlorine to! form colourless, vaporous salts with the formula MCl; 14. meet and be able to give examples to envision that the alkali metals decease more reactive as the group is descended; 15. recall the main(prenominal) hazard symbols and be able to give the safety precautions for intervention hazardous chemicals (limited to harmful, toxic, irritant, corrosive, oxidizing, highly flammable); 16. explain the...If you unavoidableness to get a effective essay, order it on our website: OrderCustomPaper.com
